  • An exemplary method for screeding cement over and locating the pipe penetration 110 by use of the indicator cap 100 of any one of the embodiments may comprise the steps of: a. Trimming or cutting the pipe projection 110 such that the open end 111 of the pipe projection 110 is level with, below, or near level to the intended surface of the concrete slab (not shown) or a finished floor level (not shown); b. Selecting an indicator cap 100 where at least one of the pipe engaging diameters (PE) or the pipe capping diameter (DC) is in accordance with the diameter of the pipe (DP); c.

  • the cutting means is selected in accordance with the material that the cap body 50 is comprised of.
  • the cap body 50 may be comprised of the resi l ient material, in this instance a Stanley knife (or a simi lar cutting apparatus) may be used to cut the capping portion 50 to provide the means for subsequent connection or access of the pipe 110.
  • the indicator cap 100 may be removed from the pipe 110 post screeding and setting of cement by the appl ication of an upward force. In this way, the open end 111 of the pipe 110 is exposed to provide the means for subsequent connection or access to the pipe 110, without cutting the capping portion 50 of the indicator cap using the cutting means.
  • step “e” of the method above may become apparent to those skil led in the art, that the use of the indicator cap 100 wherein the means for aiding location 10 is any one of the embodiments of the projection 11 comprised of the resilient material, assists in clearing cement (that is, the screeded material) from the surface 51 of the capping portion 50. That is, during the screeding process, the resilience of the projection 11 may deter screeded cement from settling on the surface 51 of the capping portion 50 by its inherent advantage to recover post screeding, thereby removing/preventing cement from settling on the surface 51 of the capping portion 50.
  • the indicator cap 100 further aids to locate the indicator cap 100 (and thus the pipe 110), particularly so in the instance that the indicator cap 100 is produced in a highly visible colour and a powered concrete levelling device (such as a helicopter trowelling machine, not shown) is used at step "e" to screed the cement.
  • a powered concrete levelling device such as a helicopter trowelling machine, not shown
  • the resilience of the projection 11 advantageously permits easier removal of the capping portion 50 in order to expose the open end 111 of the pipe 110 post screeding, as there will not be a requirement to clean cement off from the surface 51 of the capping portion 50. That is, it may be appreciated, by the resilience of the projection 11 the surface 51 of the indicator cap 100 comprises an inherent "self cleaning" function.
  • Another advantage of the method above is that it reduces the likelihood of a non-level cement slab surface around the periphery of the pipe projections 110, as the pipe projections 110 are cut or trimmed such that the open end 111 is level with the surface of the cement slab. Thereby, the use of the indicator cap 100 assists in resulting in a more visually pleasing and level concrete slab surface.
  • indicator cap 100 reduces the likelihood of the operator unintentionally damaging the pipe projections 110 during the screeding process. This is due to the pipe projections 110 being cut or trimmed such that the open end 111 is level with the intended surface of the cement slab, thereby reducing the likelihood of requirement of repair and recover to the submerged pipes.
  • Another advantage provided by the indicator cap 100 is that the capping portion 50 connected to the engagement portion 40 covers the open end 111 of the pipe 110. In this way, the potential for wet concrete to enter the open end 111 of the pipe 110 during the pouring or screeding of concrete is mitigated.
  • a further advantage provided by the use of the indicator cap 100 is that the pipe projections 110 are cut or trimmed such that the open end 111 is at or near the intended surface of the cement slab, this reduces the l i kel ihood of trip hazards on the concrete slab post the screeding operation, thus leading to a reduction in foot, shin, ankle and other injuries as a result of contact with the pipe penetrations 110.
